The altered structure of "Turner-teeth" was examined under the scanning electron microscope. The enamel surface revealed developmental disorders such as bowl-shaped pits, Tomes' process pits and enamel craters with rounded borders. On the fractured surfaces of yellowish discolored enamel, localized islands of pathological enamel were found. The enamel rods were atypically arranged and poorly mineralized. Surprisingly the prisms formed later by the same ameloblast often exhibited a entirely normal structure.
在扫描电子显微镜下检查了“特纳牙”的结构改变。牙釉质表面显示出发育障碍，如碗状凹坑、托姆斯突凹坑和边缘呈圆形的牙釉质凹坑。在发黄变色的牙釉质断裂面上，发现了局部的病理性牙釉质岛。牙釉质柱排列异常且矿化不良。令人惊讶的是，由同一成釉细胞后来形成的棱柱往往呈现出完全正常的结构。
